2007 Volvo XC70
Volvo recommends that you always drive on tires of the same brand, size,\
construction (radial), tread
pattern, load-, speed-, traction- , temperature-, and treadwear rating. \
Never drive on mixed tires, except
for brief periods when the temporary spare tire is in use.
Always use properly inflated tires of correct dimensions. Tire size and \
inflation pressures are shown on
the tire inflation pressure placards, located on the driver's side B-pil\
lar (the structural member at the side
of the vehicle, at the rear of the driver's door opening), or on the in\
side of the fuel filler door on
Canadian models.
Temporary Spare
The temporary spare tire is for temporary, low-speed, short-distance use\
only. Replace it with a full-
sized tire as soon as possible. Do not drive on the temporary spare at s\
peeds above 50 mph (80km/h) or
for distances greater than 50 miles (80 km).
Never install snow chains on a temporary spare.

Four-C active chassis system
Four-C active chassis
The FOUR-C (Continuously Controlled Chassis Concept) active chassis sy\
stem, consisting of Comfort
and Sport modes, is available as an option.
NOTE: The V70 R has a standard FOUR-C system consisting of Comfort, Sport, an\
d Advanced sport
modes. The buttons for controlling these driving modes are located in ce\
nter instrument panel, above the
ventilation system panel vents, see the illustration in the right column\
. These buttons can be pressed at
any time to change driving modes. An indicator light in the selected but\
ton will come on to indicate the
driving mode that is currently selected.
This system is based on a number of sensors that continuously monitor fa\
ctors such as the vehicle's
lateral and vertical movements, speed, and movements of the wheels. The \
sensors receive data up to 500
times per second, which is used to provide extremely fast and precise ad\
justment of each shock
absorber. The system adjusts the stiffness of the shock absorbers approx\
imately 100 times per second
Use the button in the center console to switch between the driving modes\
Comfort and Sport. This can
be done at any time.
Comfort
The Comfort mode chassis setting offers the greatest amount of shock abs\
orption and the softest ride.

This mode is recommended for long-distance driving, or when driving in s\
lippery conditions. The
indicator light in the button will be off when this mode is selected.
If Comfort mode was selected when the engine was switched off, this mode\
will still be active when the
engine is restarted.
Sport
In this mode, shock absorption is stiffer to reduce the vehicle's body s\
way during cornering and to
provide more immediate steering response. The indicator light in the but\
ton will come on to indicate that
Sport mode has been selected.
If this setting was selected when the engine was switched off, Sport mod\
e will still be active when the
engine is restarted.
Advanced sport (V70 R only)
In this mode, movement of the shock absorbers is minimal, response from \
pressure on the throttle pedal
is more direct, and body sway in curves or when cornering is sharply red\
uced.
If Advanced sport mode was selected when the engine was switched off, Sport mode will be active
when the engine is restarted.

Brake system
BRAKE Brake circuit malfunction
The brake system is a hydraulic system consisting of two master cylinder\
s and two separate brake
circuits. If a problem should occur in one of these circuits, it is stil\
l possible to stop the vehicle with the
other brake circuit.
If the brake pedal must be depressed farther than normal and requires gr\
eater foot pressure, the stopping
distance will be longer.
A warning light in the instrument panel will light up to warn the driver\
that a fault has occurred.
If this light comes on while driving or braking, stop immediately and ch\
eck the brake fluid level in the

reservoir.
NOTE: Press the brake pedal hard and maintain pressure on the pedal - do not \
pump the brakes.
WARNING!
If the fluid level is below the MIN mark in the reservoir or if a "Brake\
failure - Service urgent"
message is displayed in the text window: DO NOT DRIVE. Have the vehicle \
towed to a Volvo
retailer and have the brake system inspected.
NOTE: When the vehicle is at a standstill and the engine is idling, e.g. at a\
traffic light and the brake
pedal is depressed, the pedal may go down slightly. This is a normal fun\
ction of the power-assisted
brake system.
Power brakes function only when the engine is running
The power brakes utilize vacuum pressure which is only created when the \
engine is running. Never let
the vehicle roll to a stop with the engine switched off.
If the power brakes are not working, the brake pedal must be pressed app\
roximately four times harder
than usual to make up for the lack of power assistance. This can happen \
for example when towing your
vehicle or if the engine is switched off when the vehicle is rolling. Th\
e brake pedal feels harder than
usual.
Water on brake discs and brake pads affects braking
Driving in rain and slush or passing through an automatic car wash can c\
ause water to collect on the
brake discs and pads. This will cause a delay in braking effect when the\
pedal is depressed. To avoid
such a delay when the brakes are needed, depress the pedal occasionally \
when driving through rain,
slush etc. This will remove the water from the brakes. Check that brake \
application feels normal. This
should also be done after washing or starting in very damp or cold weath\
er.
Severe strain on the brake system
The brakes will be subject to severe strain when driving in mountains or\
hilly areas or towing. Vehicle
speed is usually slower, which means that the cooling of the brakes is l\
ess efficient than when driving on
level roads. To reduce the strain on the brakes, shift into a lower gear\
and let the engine help with the
braking. Do not forget that, if you are towing a trailer, the brakes wil\
l be subjected to a greater than
normal load.

Anti-lock brakes (ABS)
If the warning lamp lights up there is a malfunction of the ABS system (\
the standard braking system will
however function) and the vehicle should be driven cautiously to a Volv\
o retailer for inspection. The
Anti-lock Braking System (ABS) helps to improve vehicle control (stop\
ping and steering) during severe
braking conditions by limiting brake lockup. When the system "senses" im\
pending lockup, braking
pressure is automatically modulated in order to help prevent lockup, whi\
ch could lead to a skid.
The system performs a self-diagnostic test when the engine is started an\
d when the vehicle first
reaches a speed of approximately 12 mph (20 km/h). The brake pedal will pulsate several times and a
sound may be audible from the ABS control module. This is normal.
To obtain optimal effect from the ABS system, constant pressure should b\
e kept on the brake pedal. Do
not pump the brake pedal.
The switching of the ABS modulator will be audible and the brake pedal w\
ill pulsate during braking.
Please be aware that ABS does not increase the absolute braking potentia\
l of the vehicle. While control
will be enhanced, ABS will not shorten stopping distances on slippery su\
rfaces.
ABS with EBD (Electronic Brake Force Distribution)
EBD is an integrated part of the ABS system. EBD regulates the hydraulic\
pressure to the rear brakes to
help provide optimal braking capacity. The brake pedal will pulsate duri\
ng braking, which is normal.
If the BRAKE and ABS warning lights come on at the same time, this could\
indicate a fault in the brake
system.
- Stop the vehicle in a suitable place and switch off the engine.
- Restart the engine.
- If both warning lights go off, no further action is required.
- If both lights are still on after the engine has been restarted, switc\
h off the engine again and check the
brake fluid level (see
page 193 for the location of the brake fluid reservoir).
WARNING!
If the fluid level is below the MIN mark in the reservoir or if a "Brake\
failure - Service urgent"
message is displayed in the text window: DO NOT DRIVE. Have the vehicle \
towed to a Volvo
retailer and have the brake system inspected.
- If the brake fluid level is above the MIN mark, drive carefully to an \
authorized Volvo retailer and have
the brake system inspected.
Emergency Brake Assistance (EBA)
The EBA function is designed to provide full brake effect immediately in\
the event of sudden, hard
braking. The system is activated by the speed with which you depress the\
brake pedal.

Spin control (SC)
The spin control function is designed to help prevent the drive wheels f\
rom spinning while the vehicle is
accelerating.
Under certain circumstances, such as when driving with snow chains, or d\
riving in deep snow or loose
sand, it may be advisable to temporarily switch off this function for ma\
ximum tractive force.

Trailer towing does not normally present any particular problems, but ta\
ke into consideration:
l Increase tire pressure to recommended full. See section "Wheels and tire\
s."
l When your vehicle is new, avoid towing heavy trailers during the first 6\
20 miles (1000 km).
l Recommended hitch tongue load is: Trailer weights below 2,650 lbs (1,200 kg) - 110 lbs (50 kg)
Trailer weights above 2,650 lbs (1,200 kg) - 165 lbs (75 kg)
l Maximum speed when towing a trailer: 50 mph (80 km/h).
l Engine and transmission are subject to increased loads. Therefore, engin\
e coolant temperature should
be closely watched when driving in hot climates or hilly terrain. Use a \
lower gear and turn off the air
conditioner if the temperature gauge needle enters the red range.
l If the automatic transmission begins to overheat, a message will be disp\
layed in the text window.
l Avoid overload and other abusive operation.
l Hauling a trailer affects handling, durability, and economy.
l It is necessary to balance trailer brakes with the towing vehicle brakes\
to provide a safe stop (check
and observe state/ local regulations).
l Do not connect the trailer's brake system directly to the vehicle's brak\
e system.
l More frequent vehicle maintenance is required.
l Remove the ball and drawbar assembly when the hitch is not being used.
l Volvo recommends the use of synthetic engine oil when towing a trailer o\
ver long distances or in
mountainous areas.
WARNING!
l Bumper-attached trailer hitches must not be used on Volvos, nor should s\
afety chains be attached
to the bumper.
l Trailer hitches attaching to the vehicle rear axle must not be used.
l Never connect a trailer's hydraulic brake system directly to the vehicle\
brake system, nor a trailer's
lighting system directly to the vehicle lighting system. Consult your ne\
arest authorized Volvo retailer
for correct installation.
l When towing a trailer, the trailer's safety wire must be correctly faste\
ned to the hole or hook
provided in the trailer hitch on the vehicle. The safety wire should nev\
er be fastened to or wound
around the drawbar ball.
NOTE:
l When parking the vehicle with a trailer on a hill, apply the parking bra\
ke before putting the gear
selector in (P)ark (first/ reverse gear on manual transmissions).
